MFD, Manifold

Manifold MFD format is a deprecated, legacy format, used in early Manifold versions such as Manifold System Release 4.50 and earlier.   Release 4.50 and earlier Manifold versions stored drawings in an ensemble of two files, an .mdb Access database format file to store attributes, and an .mfd file to store geometry.   Both files are required.  


Manifold uses Microsoft facilities to work with Microsoft .mdb files.   If Manifold cannot import from, link to, or export to an .mdb file, that means the Windows system we are using is missing the necessary facilities.  If .mdb capability is missing, Manifold will import a legacy mfd/mdb file, but only object geometry will appear and data fields, that is, attributes, for each object will not be imported from the .mdb file.   Please see the Microsoft Office Formats - MDB, XLS and Friends topic for a solution.


A typical 4.50 project will be stored using three files:  an .mfd and .mdb pair of files for drawings, plus an .mws  workspace file that saves formatting and other project information.



To import from MFD format:


  1. Choose File-Import from the main menu.

  2. In the Import dialog browse to the folder containing data of interest.

  3. Double-click the file ending in .mfd for the data of interest.

  4. All components from the .mfd file will be imported.



We can double-click on drawings that are created to view them.   



Release 4.50 .mfd format does not save formatting information.  Formatting is saved in an .mws project file that may accompany the .mfd and .mdb files.
